German aircraft leasing firm DVB Aviation Finance Asia PTE Ltd won a legal battle against the grounded Kingfisher Airlines with the Delhi High Court asking DGCA to deregister two leased-out planes lying at Istanbul in Turkey.

Kingfisher Airlines has lost a legal battle with German aircraft leasing firm DVB Aviation Finance Asia PTE Ltd. The Delhi High Court on Monday asked the Directorate General of Civil Aviation (DGCA) to deregister two leased-out planes of the ailing carrier lying at Istanbul in Turkey.

"The petition is allowed. DGCA is directed to deregister the two aircraft which are lying outside the jurisdiction of this court," Justice Rajiv Shakdher said and asked the Vijay Mallya-owned airlines to furnish original documents of two leased aircraft to the German firm within four weeks.

Citing a previous judgement on the issue, the court said DGCA cannot withhold the deregistration of the aircraft on the ground that the airlines owe money to the government and its agencies.

"It is made clear that if any dues remain payable from the airlines, the respondent (DGCA) can take recourse to appropriate measures against respondent 2 (Kingfisher)," Justice Shakdher said.
